'following isa full, clear, and exact descrip-` tion, ysuch Aas will enable others skilled in the l artfto which it apperta-ins to make and `use the same, reference being had to the v accompanying drawings, whichvillustrate the pre-` ferred form of the invention, though' it is to nbe understood that the invention is not limitedy to the exact details of construction shown and described, as it is obvious `that various l.modifications thereof within the` .scope of the claims-will occur to persons skilled in the art.

In said drawings: y i f Figure 1 is a vertical longitudinal section taken on line 1-1 of.Fig..2, showing the yoke and contained parts 'assembled with the car underframe;

25 y Figure 2 is a plan view of the device;

Figure 3 is a front view of the same;

AFigure 4 is a vertical'transverse `section taken on line 4`-4 of Fig. 1 looking in the direction indicated by the arrow; Figure 5 is a view similar to Fig. 1 but illustrating a modification;

Figure 6 is a plan view thereof; and Figure -V7l is a vertical' transverse section taken on line 7-7 of Fig. 5;

My invention relates to draft and buffing mechanism for use in mine and other industrial cars having their understructures made up of longitudinal and transverse framing members.-

The principal object of my invention is' to provide a mechanism comprising in part certain members of the car framework.

Another object is to provide a draft and buiiinp mechanism having its supporting part slidably mounted uponand embracing associated c ar frame members.

In the drawings, 10 and 11 represent respectively the end sill and crosstie members of a car underframe, and 12 indicates the yoke member of the mechanism slidably mounted upon and enclosing the frame members 10 and 11. The yoke 12 comprises top wall portion 13, depending front and rear end or foot portions 14 and 15 having inwardly extending flanges 16 andv guide pieces 17 extending under the frame membersand resting upon and secured to thefoot anges 16. The guide pieces 17 are spaced apart as shown to receive between them an anchor strip 1S secured at its ends to the framing'members 10 and 11 for guiding the yokepin 'itsfmovements and serving to prevent lateral displacement of said yoke during service. operations. These functions may be performed with the positions of the yoke guide pieces 17 and anchor strip 18 reversed if desired; the guide .pieces n may be secured to the framing members and .the anchor strip` 18 to` the yoke footv portions 14 and 15;.but 'the disposition of the parts as shown isipreferred.I 'The guide pieces 17 are removably secured to the yoke foot flanges 16 to facilitate assembling and disassembling of the yokewith car yframing members. l A

In front of the end 10 and moving with the yoke 12 is a couplingpiece .19 havingfits body portion 2Oy secured to fthe huifing foot 14 of the yoke and provided with a protruding head portion 21 formed to receive between it andtop wall4 13 ofthe yoke 12 a coupling link 22 or other like device.

v to properly guide the thimbles in their movements, such thimbles are cored out to receivev The Afollower -thimf an alining rod 27 extending through thel foot l bearing area alforded by the thickness of the webs 26 of the framing members. The bearing brackets 29 are provided with wings 30 perforated to receive attaching means 31 for securing same to the framing members. The bearing areak thus provided for each follower thimble will prevent relative displacement of resilienty element 23 and the follower thimbles 24.

It will be noted that the follower thimbles 24C are cylindrical in form and providedadjacent one end thereof with an enlarged portion 32 adapted to limit movement of said thimbles in one direction under the expansive action of the resilient element 23, and

serves as a seat for said resilient element which, in the form shown, is arranged to receive protruding portions 33 on the thimbles.

T he mechanism as shown is in position to respond to either draft or bnfng operations. A baiting operation against the mechanism shown in Fig. 1 will canse yoke 12 to move rearwardly, causing the bnfiing foot 14 to bear aginst adjacent follower thimble 24, forcing enlarged portion 32 thereof to re cede from the web of the end sill and compress spring 23. During this operation, yoke 12, alining rod 27, and the follower thimble adjacent end sill 10 will have moved against the expansive action of the spring, but the yoke top wall portion 13, guide pieces 17, and alining rod 27 will not have been subjected to compressive stresses. under reverse movement, a pull on draft piece 19 will cause yoke foot portion 15 to approach crosstie 11 and force the enlarged portion 32 of adjacent follower thimble 24 against the spring.

What I claim is:

1. The combination with an end sill and adjacent crosstie member of a car underframe, of a draft and bnfling mechanism comprising a yoke member having` depending foot portions embracing said framing members, guide means extending under the framing members and connecting said foot portions, and yoke anchorage means connecting said end sill and crosstie member and engaging said guide means.

3. The combination with an end sill andv adjacent crosstie member of a car underframe, of a draft and bnl'ling mechanism comprising a yoke member having guide means extending under said framing members, and yoke anchorage means connecting said crosstie and end sill and engaging said gnide means.

4. In a draft and bnfiing mechanism for cars having framing members, a yoke member having guide means extending under said framing members, depending foot portions on the yoke embracing the framing members and secured to said guide means, and yoke anchorage means connectingsaid framing members and adapted for engage ment with said guide means.

5. The combination with an end sill and adjacent crosstie member of a car underframing, of a draft and bufling member having depending foot portions embracing said framing members, a resilient member carried by said framing members, and alining means engaging said foot portions and resilient member.

6. The combination withI an end sill and adjacent crosstie member of a car underframing, of a yoke member having depending foot portions embracing said framing members, a resilient member carried by said framing members, and alining means connecting said foot portions and associated with said resilient means.

In witness whereof I have hereunto set my hand.

VICTOR VVILLOUGHBY.
